“Beyond the Jordan, in the land of Moab, Moses undertook to explain this law, saying,”
Deuteronomy 1.5 ESV
With his last words, Moses was anxious to remind the people of what God had done for them and urge them to obey his laws. So he undertook or “resolved” (JUB) to declare God’s law to them.
The verb “undertake” means to decide to begin something. Moses saw this as what he ought to do in his final days. What ought to be my decision at this juncture in my life?
